Collaborative Filtering

The topic of collaborative filtering was brought up in class today. This is great for businesses to try and connect with users and recommend items which they may like. Although, as a user I feel my information is being used without my consent. There are huge privacy concerns with collaborative filtering. Even when I come back to a site like amazon it remembers me and is storing information on me. I feel my privacy is being invaded and that my permission should be asked of in order to store information about what I like, buy, or am interested in. The internet and technologies which go along with it just seem to not be a safe in keeping ones identity/likes ect safe .

This topic brings me to the idea of Facebook. Facebook is being used a networking tool, but again has the same privacy concerns and can be detrimental to many. Those who post interesting pictures of partying should really question if they want that information to portrayed of them especially to potential employers. It seems if something is put on the internet about you it will be there forever.
